RAILROAD-SCALE.

SPECIFCATION forming part of Letters Patent No. 723,184, dated March 1'7. 1903.

Application filed January l5. 1901. serial No. 43401. (No model.)

To rif/ZZ whom, zlz'; may concern:

Be it known that I, MICHAEL EDUARD REI- SERT, a subject of the German Emperor, and a resident of Hennef-on-the-Sieg, in the Province of Rhineland and AKingdom of Prussia, in the German Empire, have invented certain new and useful Improvements in Railroad- Scales, of which the following is a specification.

The present invention relates to improvements in railroad-scales for weighing large quantities of merchandise-such as coal, ore, vegetables, and like materials-which are brought upon and respectively removed from lthe platform or bridge of the railroad-scale in suitable trucks, vehicles, or Wagons running upon rails and carrying not less than a predetermined minimum weight or load.

The object of the improvements is to provide means which allow that only such 'wagons carrying a load above the said minimum weight can be driven over the bridge or platform of the scale and which also prevent a vehicle just removed from the bridge or platform from being run back upon the platform and weighed once more on fraudiilent purpose.

'lhe above object is attained by means of a blockingdevice in combination with the railroad-scale and capable of being released by running upon the scale bridge or platform a wagon having a load in excess of the predetermined minimum weight. By this disengagement of the blocking device a suitable power device-such as a weighted lever, spring, orthe like-is allowed to act upon and to reverse a suitable stop-arm or stop-arms arranged in the path of the wagon that is to say, in front and at the rear of the scale bridge or platform-in order to clear the railtrack in front of the wagon and to bar the same at the rear of the latter, so that the wagon can be moved forward, but will be prevented from rear-ardV movement. In connection with the blocking device there is arranged a locking device which retains the said blocking device, or more properly the stop-arms, after Lheir reversal in the blocking position until the wagon is entirely passed `rai lroad-scale.

over or removed from the scale bridge or platform. After the removal of the load from the platform the scale mechanism of the railroad-scale returns into its initial position. whereby the locking device 4is released and the blocking device at the same time caused to return also into its initial position. By this return motion of the blocking device the stop-arms are again reversed, thus permitting another truck or Wagon to be run into position upon the scale bridge or platform.

With this end in view the present invention consists in certain novel features of construction and combination of parts, as will be hereinafter fully described with reference to the accompanying sheets of drawings, wherein- Figure 1 is a longitudinal vertical section, and Fig. 2 a cross-section, of the improved In both of these figures the parts are in position they assume when a wagon carrying less than a predetermined minimum load is on the scale bridge or platform. Fig. 3 is a similar section to Fig. 2, showing the blocking device in the reversed position, a wagon having a load above the predetermined minimum Weight being on the scale bridge or platform, the. lever mechanism connecting the scale bridge or platform with the pendulum-scale forming part of the railroad scale being removed for sake of simplicity. Fig. et is a plan of Fig. 3 as it appears after the removal of the scale bridge or platform, and Fig. 5 is a plan view of the lever system. Fig. 6 is a front elevation of the registering mechanism on a larger scale, the front plate being partly broken away to show the inner gearing; and Fig. 7 is a sectional plan view on line I II of Fig. 6.

Similar characters refer to similar parts throughout the several figures.

The vehicles or wagons to be weighed run on rails b, in the track of which is arranged the weigh bridge or platform o., the latter being provided with corresponding rails b. The frame c, carrying the platform d, rests by means of knife-edges c upon two levers d, the outer ends d' of which are supported by the aid of knife-edges d2 from suitable knifeed ge-bearing brackets A', extending fromA the wall of a box or casing A, inclosing the lever mechanism of the scale. The inner ends of the levers (Z are suspended from suspension-loops (Zi, carried by arms e of a platform-lever e. One end of this lever rests by means of a knife-ege e2 upon a knife-edge bearing on a bracket A2 of the box A, while the other end, extending through a slot A3 into an adjacent box B, is suspended by means of a knife-edge e3 from a knife-edge bearing on a barf of a pendulum-scale, forming part of the railroad-scale. The box B serves asa receptacle or casing for a part of the blocking device and its locking means (to be described later on) and forms at the same time the support for the standards C, carrying the pendulum-scale. The bar fis suspended from a steel band h, passing over a pulley g and having attached to its other end a bar 1I, provided with a weight vl'. The shaft g' of the pulley is fulcrumed by means of knife-edges on suitable brackets secured to the proximate faces of the standards C. The bulb-shaped end 'Z2 of the bar Z, engaging a recess 3 of a weight 114, is thereby connected to the latter weight in such a manner that the weighted bar Z t" Q12 can perform a differential motion with respect to the weight i4, which ordinarily rests upon a bracket B2 of the box B.

Connected with the pulley g or its shaft g', respectively, is a double armed weigh ted lever Zt, adapted to operate by means of a friction-roller 7c the push-rod k2 of a suitable registering' device D. The upper counter'of the registering mechanism D records and indicates the constant minimum loads, the lower counter' the variable excesses above the predetermined minimum load. Each time the weighted lever lo rocks to the left its frictionroller k3 strikes against a weighted lever l. The rocking motion of this lever l is imparted by means of a connecting-rod 2, a lever 3, and a pawl it, pivoted thereto, to the ratchetwheel 5, which drives` the gear-wheels 7 of the upper counter. The return movement of the lever connection is effected automatically by the weighted lever l as soon as the lever Za swings to the right. When thelever Z: is rocked to the right, its friction-roller 7c displaces a push-rod Z152, provided with a rack 8, engaging a pinion 9. This pinion operates by means of a pawl 10 a suitable ratchetwheel ll, keyed on the same shaft as the toothed wheel l2, engaging the driving-wheel 13 of the lower counter. The push-rod is brought back into its initial position each time the lever .7c swings to the left. The combination of the weighted steel band Zz with suspension-bar f, the pulley g, the weighted lever Zt', the push-rod 7.32, and the registering device D forms the pendulum-scale proper. The construction and operation of such pendulum-scale are well known and need, therefore, no detailed description. The combination of the said pendulum-scale with the abovemechanism, carrying the described lever weigh bridge or platform and acting upon the barf of the pendulum-scale, forms the railroad-scale proper. The construction and operation of such scales are likewise well known and need also no further explanation.

The blocking device, mounted within the boxes or casings A and B, consists of a rocking shaft m, journaled within the walls of the boxA and provided near its ends with oppositely-directed arms n and n', respectively. To the free ends of these arms are' articulated slide arms or bolts ZandZ, respectively, which are vertically guided in suitable guides provided on the box A. When the shaft m is rocked in one direction, the slide-bolt or stop-arm Z is lowered out of the path of the wagon-wheels W, while at the same time the stop-arm Z is raised to act as a stop for the said wheels W. When the shaft m is rocked in the other direction, then the stop-arm Z is lowered and the stop-arm Z raised. By rocking the shaft m in one or the other direction the stops Zand Z for the wagon will therefore be reversed alternately in order to allow a wagon to be moved on and across the scaleplatform or to prevent a wagon being moved on and then backed off said platform. In the position the parts are shown in Figs. l and 2 the removal of the wagon from the platform of the railroad-scale is barred by the raised stop-arm Z. The rocking or oscillating of the shaft m for lowering the stop-arm Z is effected by the influence of a weighted arm 0 o', attached to the shaft fm, as soon as said weighted arm or the shaft m, respectively, is released by the deflection of a toggle-joint P, which is composed of a lever-p and a linkp, articulated at p4. The lever p is pivoted at p2 in a support or bracket B', while the free end of the link in is pivotally connected at p3 to an arm m', extending from the shaft m. The detiected position of the toggle-joint P and the therefrom resulting reversed position of the stop-arms Z and Z are represented in Figs, 3 and il. The toggle-joint is operated and deiiected at the required time by the barfof the pendulumscale, as will be explained later on. In order to prevent shocks and the like imparted to the scale from causing a premature deflection of the toggle-joint, this latter is in its position of rest slightly deflected toward the opposite side and rests with its lever p upon the edge q of the slot A4. (See Fig. 2.)

When the platform is loaded with a wagon containing exactly or less than the desired minimum weight, such weight will slightly draw down, by means of the levers d e, the

suspension-bar f, and thereby7 lift or raise the A weighted bar M' i2 into the position shown in Fig. 2, the bulb t2 moved upward in the space or recess Z3 of the weight i4,- but as the weight t4 corresponds to the predetermined minimum weight or load itoverbalances or balances at least the weight of the wagon on the platform and will not be raised from its support B2. The slight downward motion of the bar IOS IXO

IZO

f is not sufficient to allow that its pin f acts upon an arm fr of the toggle-leverp and defiects thereby the toggle-joint P. This toggle-joint remains rather at rest, while at the same time the raised stop-arm Z prevents the procedure of the wagon carrying less than the predetermined minimum load from the platformthat is to say, the passing or running of such wagon across the platform of the railroad-scale without weighing and recording their contents. The slight downward motion of the barfimparts consequently to the lever 7c likewise but a small amplitude in the direction, of the arrow shown in Fig. 2, so that the friction-roller Zt does not come in contact with the push-rod k2 and is not caused to operate the registering device D. These positionsof the parts are shown in Figs. l and 2. vWhen, however, a wagon carrying a load above the predetermined minimum load is run upon the platform, also the weight 714 is raised from its support B2, and the pendulum-lever Za in consequence of the greater travel of the steel band h and greater rotation of the pulley g caused to move through a greater amplitude and to operate the pushrod 7a2 of the registering device in well-known manner. In such a case the .barfperforms, of course, a greater downstroke, for instance, until it assumes the position shown in dotted lines, Fig. 3. By this extent of movement of the bai-fils pin or tappet f is caused to press upon the arm 7^ and to turn the latter downward, thereby deflecting the toggle-joint upward-that is to say, through the straightcned position toward the opposite side into the position indicated in Fig. 3. At the same time the arm 0, owing to its weight o, rocks the shaft m now released by the deliection of the toggle -joint and reverses thereby the stop-arms Z and Z', the stop-arm Z being then lowered and the stop-arm Z raised, Figs. 3 and 4. The vehicle or Wagon upon the rails b of the platform can then be moved forward, but the rearward movement thereof will be prevented by the raised stop-arm Z. In the reversed position shown in Figs. 3 and 4. the stop-arms Zand Z' will remain until the vehicle or wagon has been removed'entirely from the platform of the railroad-scale. As soon as the rst pair of wheels W of the wagon leaves the platform the whole system of the railroad-scale commences to return into its initial position until-the weight t is again seated upon its support B2-that is to say, until the bars 7l and f have returned into the positions shown in Figs. l and 2. The mechanism of the railroad-scale now remains at rest until the second pair of wheels of the wagon has left the platform, as the weight t" corresponds only to the weight of the scale mechanism and is but capable to return the scale mechanism when fully unloaded'into its initial position. As soon as the wagon is cntirely removed from the platform the weighted bar t' t" t2 descends into the recess t3 of the weight t4 and raises at the same time the bar f. The tappetf2 of the ascending barfacts from below against the arm r and turns the latter upward. The toggle-joint P is hereby straightened and respectively slightly defiected downwardly, while the shaft 'm is rocked in the opposite direction, the stoparm Z raised, and the stop-arm Z' loWered,-the whole railroad-scale mechanism being thus returned into its normal position of rest. As the toggle-joint is so arranged as to be very near the point at which deflection takesplace, it will require onlya slight force or power to start it, and the operation of the weighing will not be affected; but nevertheless the straightened toggle-joint P locks the rocking shaft m so reliably that it will be impossible to forcibly depress the raised stop-arm Z with a view to running a wagon having less than the predetermined load over the platform. In order to prevent that after the deflection of the toggle-joint the then-raised stop-arm Z may be'forcibly depressed with a view of backing the last wagon off the platform and then bringing it again forward for reweighing, a further locking device is provided, which consists of a pawl or hook s, adapted to engage an arm t of the lever p of the toggle-joint and to thus lock the said togglejoint in its deiiected position. (See Fig. 3.) A straightening of the toggle-joint and respectively a rocking of the shaft m and reversing of the stop-arms Z and Z is only possible after the nook s has been disengaged from the arm t. This disengagement, however, takes place only after the load has been removed from the platform-. viz., when the second pair of wheels of the wagon hasleft the platform-by the return or ascending movement of the bar f, the tappet f3 of which strikes against the hook s and lifts it off from the top of the arm t, Fig. 3, whereupon the toggle-joint is straightened by upward movement of the tappet f2, as already explained above.
